[Current status and clinical experience in the treatment of tracheobronchial stenoses with self-expanding metallic stents].
The development of symptomatic stenosis in the bronchial tree can lead to high risk asphyxia. The implantation of metallic prostheses (stents) can provide palliative resolution of stenosis and alleviate the acute symptoms of these patients. We assess the efficacy of expandable metallic stents for treating various types of tracheobronchial stenosis. Sixteen Wallstent type expandable metallic prostheses were implanted in 16 patients with tracheobronchial stenosis (12 malignant and 4 benign) in the interventional radiology unit under fluoroscopic and endoscopic guidance. The prostheses were placed correctly and no complications were observed, such that symptoms improved immediately. Three patients with post-intubation stenosis required additional treatment with laser therapy during follow-up examinations. All the patients with malignancies died from the underlying disease, but with open airways and no tracheal symptoms. Metallic prostheses are a valid alternative for palliative treatment of malignant tracheobronchial stenosis.
